. >> colin clark, a terrorism analyst at the rand corporation, he's in pittsburgh tonight, and colin, what does this mean for the investigation? >> i think that it means the man in white is still on the loose, that should be a concern for a number of reasons. one, we saw what happened just recently when salah abdelslam was on the run for four months. he was able to reconstitute the paris cell and strike again, this time in brussels. >> collin, what's wrong, what's going on in brussels that the authorities weren't onto this, didn't do more sooner and faster? >> yeah, clearly, there's a high-level of dysfunction within brussels and belgium. part of it is a lack of manpower and resources and are there are too many suspects to survey. brussels has fighters going to syria, and some have returned home. and it's the highest rate of foreign fighters traveling to the middle east. >> so moving forward, how can that change? what can they do to change the situation in belgium? to change the situation in france, in germany, where they pay more attention to people who might be suspected terrorists?
